Arterial Blood Gas Indications: An ABG is ordered as a way to assess or manage a patient’s respiratory and metabolic acid/base balance. The test assesses the pH of a patient’s blood and is used as an indicator for the particular cause of the acidosis or alkalosis. An ABG is also used to measure adequacy of treatment for an acid/base balance. An ABG can also be used in the measurement of adequacy of oxygenation. Type of Test and testing procedure: An ABG is usually acquired through
Scientists have been trying to create artificial blood since 1883 (Indian J Crit Care Med. 2008 Jul-Sep). Using real blood for medical causes has it’s problems, the blood used must be compatible with the patient, if it is not, it can cause sickness to the patient and their condition may escalate. This is just one of the many complications with using real blood. Red Blood Cells, White Blood Cells, Plasma and Platelets are the main products extracted from donated blood, each of these products are used for something
deoxyhemoglobin is not louded with O2 . Blood in arteries is brighter red than the blood in veins. Hemoglobin molecule has four units of globin in addition to four units of heme. Estimation of serum Hb is a test that measures the level of free Hb in the liquid part of the blood (the serum). This test is done to diagnose or monitor the severity of a low RBC count caused by the abnormal breakdown of RBCs). Standard blood tests can also be performed on the blood that extracted from the arteries, like
tests are distinct in emphysema in comparison to chronic bronchitis. In the case of R.S. the arterial blood gas (ABG) values are the following: pH=7.32, PaCO2= 60mm Hg, PaO2= 50 mm Hg, HCO3- = 80mEq/L. R.S.’s laboratory findings are indicative of chronic bronchitis, where the pH and PaO2 are decreased, whereas PaCO2 and HCO3- are increased, when compare to normal indices. Based on the arterial blood gas evaluation, the physician can deduce that the increased carbon dioxide is due to the airway obstruction
caters for the sector of users that require fast results from patient samples that would otherwise be sent to a dedicated remote laboratory (Willmott and Arrowsmith, 2010). According to Junker et al. (2010), a range of tests including blood glucose measurement, blood gases and electrolytes, urea, creatinine, troponin, bilirubin, and coagulation testing can be carried out by POCT. Junker et al. (2010), state that the main uses of POCT devices are in hospitals and medical practices, however, they are
(Cretikos, Bellomo, Hillman, Chen, Finfer & Flabouris, 2008). Acid-base is the most protected homeostatic mechanism in a patient’s body and is altered by many different things, such as sepsis, with respiratory rate often compensating a change in the blood pH. Respiratory rate can also show the effect of some mediations such as opiates decreasing respiratory rate and conscious level (Cretikos et al., 2008). In conclusion, while all vital signs are taught respiratory rate is the least accurately taken
Rio Grande Valley District of the Texas Society for Respiratory Care hosted a spectacular event with many great speakers. We were able to learn so much information about asthma, mechanical ventilation, current values pertaining to the Rio Grande Valley, and ventilator graphics. The speakers were very enthusiastic throughout their presentation and we were able to gain a lot of information. We were able to also see many booths in which included various and new mechanical ventilators available, CPAP/
Fifteen years ago when I started my career as a respiratory therapist, the technology that was used daily by a therapist was a desktop computer; which use was limited to small task like printing a list of patients, doctors orders, and inserting charges of the therapies that were performed. The computer was basically used as a calculator and a printer. Fast forward to today, in the information and digital age where the computer is an essential tool in healthcare. Advancing my knowledge in digital

The aim of this project is to make the diagnosis more accurate and prevent doctors’ mistakes, by developing an application that gets the results of the blood investigations and directly gets out the diagnosis that corresponds with the results.

supply is determined by the hearts ability circulate blood, oxygen content present in blood, and the capacity of blood to transport oxygen (Gillespie, 2012). Cardiac output is determined by the heart rate and stroke volume, where stroke volume is the amount of blood ejected from the heart with each contraction (Gillespie, 2012). Preload, afterload, and contractility all affect cardiac output (Gillespie, 2012). Preload. Preload is the volume of blood in the ventricles at the end of diastole (Gillespie
Introduction Dilated cardiomyopathy (DCM) is “a syndrome characterized by cardiac enlargement and impaired systolic function of one or both ventricles.”4(1175) Through medical technology and proper medical regimen, people afflicted with this syndrome today, are living longer and are undergoing surgeries that may not be cardiac-related. Therefore, anesthesia providers may encounter increasing amounts of patients with DCM as compared in the past. As anesthesia providers, it is important to have an
with the respiratory compromise as a result of incomplete airway development (Huether & McCance, 2012). The purpose of this paper is to describe the pathophysiology mechanisms of chronic asthma and acute asthma exacerbation, and explanation of arterial blood gas pattern during an asthma exacerbation. Also, explain how age might impact pathophysiology of asthma and asthma exacerbation. The diagnosis and treatment plan needed to relieve the presented signs and symptoms will be reviewed. Lastly, the construction
Disease The patient in discussion has a past diagnosis of chronic obstructive pulmonary disease (COPD), with a history of environmental and personal risk factors that contributed to his diagnosis. COPD is a chronic inflammatory lung disease that affects gas exchange and oxygenation of all tissues. A common complication is cardiac failure (Ignatavicius & Workman, 2016, p. 558). A thorough assessment combined with laboratory and diagnostic tests will determine the appropriate nursing interventions and treatment
capacity to ventilate and oxygenate the blood like it should (Aitken, Elliott & Chaboyer 2012). While mechanically ventilatored, laying Mr J supine or even a back rest of 15-30 degrees puts him at greater risk of developing VAP than he would in the semirecumbent 45 degrees position (Alexiou et al, 2009). For prone position see appendix 3. However, in the hemodynamically compromised patient, sitting the patient up to 45 degrees can cause drops in mean arterial pressure and central venous oxygen saturation
from a lack of buffering or excess of acid. There are several types of metabolic acidosis. Metabolic acidosis starts in the kidneys. Diabetic acidosis happens in diabetic patients with poor control over their condition. Ketones build up and turn the blood acidic if the body lacks sustainable insulin. Hyperchloremic acidosis is a result from a decrease of sodium bicarbonate. Diarrhea and vomiting
which it normally occupies” said by the Merriam-Webster medical dictionary. TGA is a congenital defect which means it is present at birth. The arteries being switched causes there to be two different blood flows instead of one. The body receives deoxygenated blood and the lungs receive the oxygenated blood. Transposition Great is a rare defect but it is serious. It is diagnosed within the first hours to weeks of birth. The signs and symptoms of TGA are blueness of the skin, trouble
hydrogen at these levels. While ascending, the pressure decreases and the nitrogen is breathed out of our bodies but if the ascend happens too quickly for the hydrogen to be breathed out, if forms bubbles (like opening a soda fast) that can attach to blood and tissues. The main factor affecting it is the reduction in ambient pressure for example having rapid ascents or deep/long dives. Age is closely related to this as older people tend to have a higher risk of sickness because older people tend to have
A complete blood count was done for this patient upon admission in order to give a baseline to help guide the patient’s care. The blood count also can show how the hematological system was affected by the trauma that the patient suffered in the motor vehicle accident he was in. If the patient was hemodynamically unstable, he may have needed blood transfusions to bring the blood counts up. In later tests, the patient had an increase in white blood cell counts could indicate infection, possibly of
